Any embodiment or design schemedescribed as “exemplary” or “for example” in the embodiments of thisdisclosure should not be construed as being more preferred oradvantageous than other embodiments or design schemes. To be precise,the use of the term such as “exemplary” or “for example” is intended topresent a related concept in a specific manner.

The following describes the embodiments of the present disclosure withreference to the accompanying drawings. A measurement method, userequipment, and a network side device provided in the embodiments of thepresent disclosure may be applied to a wireless communications system.The wireless communications system may be a 5G system, an evolved LongTerm Evolution (Evolved Long Term Evolution, eLTE) system, or asubsequent evolved communications system.

FIG. 1 is a structural diagram of a measurement control system accordingto an embodiment of the present disclosure. As shown in FIG. 1 , themeasurement control system includes user equipment (User Equipment, UE)11 and a network side device 12. The user equipment 11 may be a mobilecommunications terminal, for example, UE side devices such as a mobilephone, a tablet computer (Tablet Personal Computer), a laptop computer(Laptop Computer), a personal digital assistant (personal digitalassistant, PDA), a mobile Internet device (Mobile Internet Device, MID),or a wearable device (Wearable Device). It should be noted that aspecific type of the user equipment 11 is not limited in this embodimentof the present disclosure. The network side device 12 may be a 5Gnetwork side device (for example, a gNB or a 5G NR NB), or may be a 4Gnetwork side device (for example, an eNB), or may be a 3G network sidedevice (for example, an NB), or a network side device in a subsequentevolved communications system. It should be noted that a specific typeof the network side device 12 is not limited in this embodiment of thepresent disclosure.

In a 5G NR system, in addition to a connected mode and an idle mode, anindependent radio resource control (Radio Resource Control, RRC) mode isalso introduced, which is referred to as an inactive mode (inactivemode). Herein, the idle mode and the inactive mode may be referred to asnon-connected modes.

In a related technology, a rapid activation and deactivation function isintroduced to an enhanced carrier aggregation technology in an LTEenhancing carrier aggregation utilization (Enhancing CA Utilization,EuCA) project. The rapid activation and deactivation may refer to rapidcarrier activation and deactivation that is applicable to an eLTEsystem, or may refer to rapid carrier activation and deactivation thatis applicable to a 5G NR system, or may refer to rapid bandwidth part(Bandwidth Part, BWP) activation and deactivation that is applicable toa 5G NR system, or the like.

For rapid carrier activation and deactivation, the following method isprovided in the related technology:

Based on an instruction of a network side device, the user equipmentperforms measurement in the non-connected mode, and immediately reports,after the user equipment enters the connected mode, that there is anavailable measurement result. When the network side device requests theuser equipment to report a measurement result, the user equipmentreports the measurement result. In this way, the network side device canquickly configure an SCell of the user equipment and activate the SCellbased on the measurement result reported by the user equipment. Specificsteps are as follows:

The network side device indicates measurement configuration informationof the user equipment in the idle mode in a system broadcast messagesystem information block type 5 (System Information Block Type 5, SIB5)and/or an RRC connection release message (RRC Connection Release). Thenetwork side device indicates, in a system broadcast message systeminformation block type 2 (System Information Block Type 2, SIB2), thatthe network side device can receive the measurement result of the userequipment in the idle mode. When the user equipment determines thatthere is the measurement result in the idle mode, and the systembroadcast message SIB2 indicates that the network side device canreceive the measurement result of the user equipment in the idle mode,the user equipment reports, to the network side device and in RRCconnection setup complete (RRC Connection Setup Complete) or RRCconnection resume complete (RRC Connection Resume Complete) in the Msg5,that there is an available idle mode measurement result indication. Thenetwork side device adds an idle mode measurement result request (idleMode Measurement Req) to a UE information request (UE InformationRequest) message to request an idle mode measurement result from the UE.After receiving the idle Mode Measurement Req carried in the UEInformation Request, the user equipment adds an idle mode measurementresult (meas Results idle) to a UE information response (UE InformationResponse) message, to report the measurement result to a base station.The network side device quickly configures and activates the SCell ofthe user equipment based on the idle mode measurement result reported bythe user equipment.

For the foregoing process, refer to FIG. 2 .

In a related technology, the network side device indicates only themeasurement configuration information of the user equipment in the idlemode. As described above, the network side device indicates themeasurement configuration information of the user equipment in the idlemode in the system broadcast message and/or the RRC connection releasemessage. However, for another RRC non-connected mode, that is, theinactive mode, a carrier aggregation enhancement technology has aproblem of relatively long activation time due to a lack of acorresponding measurement configuration solution.

Based on this, the embodiments of the present disclosure aim to providea measurement control system shown in FIG. 1 , and provide a measurementmethod applied to the measurement control system. The method is asfollows:

receiving first measurement configuration information sent by a networkside device; and

performing measurement in an inactive mode based on the firstmeasurement configuration information, to obtain a measurement result;where

the first measurement configuration information is used at least in theinactive mode.

In this way, in this embodiment of the present disclosure, the networkside device sends measurement configuration information that is used atleast in the inactive mode to user equipment, so that the user equipmentcan perform measurement in the inactive mode based on the measurementconfiguration information. Because the user equipment can performmeasurement in the inactive mode, the network side device can quicklyconfigure an SCell of the user equipment and activate the SCell based onthe measurement result in the inactive mode that is reported by the userequipment. It can be learned that this embodiment of the presentdisclosure helps support enhanced rapid carrier activation anddeactivation, so that an enhanced rapid carrier activation anddeactivation technical solution can be improved.

In addition, in a case in which the network side device indicates, forexample in a system broadcast message and/or an RRC connection releasemessage, the measurement configuration information of the user equipmentin the inactive mode, when the user equipment enters an idle mode fromthe inactive mode, whether the measurement configuration informationconfigured for the inactive mode is applicable to measurement performedby the user equipment in the idle mode is also a problem that needs tobe resolved in the embodiments of the present disclosure.

To resolve the foregoing problem, the embodiments of the presentdisclosure are specifically described by using a measurementconfiguration solution of the user equipment in the non-connected modethat is indicated by the network side device and a related measurementbehavior of the user equipment in the non-connected mode.

FIG. 3 is a flowchart of a measurement method according to an embodimentof the present disclosure.

The measurement method in this embodiment of the present disclosure isapplied to user equipment. In this embodiment of the present disclosure,the user equipment may be understood as user equipment that has ameasurement capability in a non-connected mode. A 5G NR system is usedas an example. The non-connected mode of the user equipment may be anidle mode, or may be an inactive mode. In other words, the userequipment is user equipment that has an idle mode and/or inactive modemeasurement capability.

As shown in FIG. 3 , the measurement method includes the followingsteps.

Step 301: Receive first measurement configuration information sent by anetwork side device, where the first measurement configurationinformation is used at least in an inactive mode.

In this step, the first measurement configuration information may beincluded in a system broadcast message SIB5 and/or a radio resourcecontrol RRC connection release message, or the network side device mayconfigure the first measurement configuration information in a systembroadcast message SIB5 and/or an RRC connection release message.

The first measurement configuration information is used at least in theinactive mode, and may include a plurality of different implementations.For example, the first measurement configuration information may be usedonly in the inactive mode; or the first measurement configurationinformation may be further used in another non-connected mode such as anidle mode in addition to the inactive mode.

The first measurement configuration information may include at least oneof the following items:

measurement duration;

a measurement frequency;

a measurement bandwidth (Bandwidth) or bandwidth part (Bandwidth part);

a valid measurement area, for example, a cell identity (ID) list, aphysical cell ID (Physical Cell Identity, PCI) list, a subset or a fullset of a radio access network notification area (Ran Notification Area,RNA) ID list, or a subset or a full set of a core network tracking area(Tracking Area, TA) ID list;

a target measurement area, for example, a cell ID list, a PCI list, asubset or a full set of an RNA ID list, or a subset or a full set of aTA ID list;

a measurement type, for example, any one or a combination of referencesignal receiving power (Reference Signal Receiving Power, RSRP),reference signal receiving quality (Reference Signal Receiving Quality,RSRQ), and a signal to interference plus noise ratio (Signal toInterference plus Noise Ratio, SINR); and

a measurement reporting threshold, for example, any one or a combinationof an RSRP threshold, an RSRQ threshold, and an SINR threshold.

Step 302: Perform measurement in the inactive mode based on the firstmeasurement configuration information, to obtain a measurement result.

In this step, the user equipment can perform measurement in the inactivemode based on the first measurement configuration information sent bythe network side device, and may obtain the measurement result in theinactive mode. The user equipment can perform measurement at least inthe inactive mode, which helps support enhanced rapid carrier activationand deactivation, thereby improving an enhanced rapid carrier activationand deactivation technical solution.

The measurement result measured by the user equipment in the inactivemode may include any one or a combination of the following items:

a measurement identifier (meas Id), a measurement frequency, RSRP, RSRQ,a physical cell identity (Physical Cell identity, PCI), a cell globalidentity (Cell Global Identifier, CGI), a tracking area code (TrackingArea Code, TAC), and a public land mobile network identifier list(Public Land Mobile Network Idlist, PLMN Idlist).

Optionally, the first measurement configuration information is furtherused in an idle mode.

The method further includes:

performing measurement in the idle mode based on the first measurementconfiguration information.

In this optional implementation, the network side device may configure,in the system broadcast message SIB5 and/or the RRC connection releasemessage, measurement configuration information that is applicable to twonon-connected modes: the idle mode and the inactive mode. In otherwords, the first measurement configuration information is applicable toboth the inactive mode and the idle mode.

In this way, in both the inactive mode or the idle mode, the userequipment can perform measurement based on the first measurementconfiguration information, and may separately obtain measurement resultsin the idle mode and the inactive mode. The user equipment can performmeasurement in both the inactive mode and the idle mode based on thefirst measurement configuration information, so that the network sidedevice can quickly configure an SCell of the user equipment and activatethe SCell based on the measurement result in the inactive mode or theidle mode that is reported by the user equipment. It can be learned thatthis embodiment of the present disclosure helps support enhanced rapidcarrier activation and deactivation, so that an enhanced rapid carrieractivation and deactivation technical solution can be improved.

The first measurement configuration information may include at least oneof the following items:

measurement duration;

a measurement frequency;

a measurement bandwidth or bandwidth part;

a valid measurement area, for example, a cell ID list, a PCI list, asubset or a full set of an RNA ID list, or a subset or a full set of aTA ID list;

a target measurement area, for example, a cell ID list, a PCI list, asubset or a full set of an RNA ID list, or a subset or a full set of aTA ID list;

a measurement type, for example, any one or a combination of RSRP, RSRQ,and an SINR; and

a measurement reporting threshold, for example, any one or a combinationof an RSRP threshold, an RSRQ threshold, and an SINR threshold.

The measurement result measured by the user equipment in the inactivemode may include any one or a combination of the following items:

a meas Id, a measurement frequency, RSRP, RSRQ, a PCI, a CGI, a TAC, anda PLMN Idlist.

Optionally, the first measurement configuration information is used inthe inactive mode.

The method further includes:

receiving second measurement configuration information sent by thenetwork side device; and

performing measurement in an idle mode based on the second measurementconfiguration information; where the second measurement configurationinformation is used in the idle mode.

In this optional implementation, the network side device may configure,in the system broadcast message SIB5 and/or the RRC connection releasemessage, respective measurement configuration information for the idlemode and the inactive mode. In other words, the first measurementconfiguration information is only applicable to the inactive mode, andthe second measurement configuration information is only applicable tothe idle mode.

In this way, when the user equipment is in the inactive mode, the userequipment needs to perform measurement based on the first measurementconfiguration information. When the user equipment is in the idle mode,the user equipment needs to perform measurement based on the secondmeasurement configuration information. The user equipment may separatelyperform measurement in the inactive mode and the idle mode based onrespective measurement configuration information, so that the networkside device can quickly configure an SCell of the user equipment andactivate the SCell based on the measurement result in the inactive modeor the idle mode that is reported by the user equipment. It can belearned that this embodiment of the present disclosure helps supportenhanced rapid carrier activation and deactivation, so that an enhancedrapid carrier activation and deactivation technical solution can beimproved.

The first measurement configuration information may include at least oneof the following items:

measurement duration;

a measurement frequency;

a measurement bandwidth or bandwidth part;

a valid measurement area, for example, a cell ID list, a PCI list, asubset or a full set of an RNA ID list, or a subset or a full set of aTA ID list;

a target measurement area, for example, a cell ID list, a PCI list, asubset or a full set of an RNA ID list, or a subset or a full set of aTA ID list;

a measurement type, for example, any one or a combination of RSRP, RSRQ,and an SINR; and

a measurement reporting threshold, for example, any one or a combinationof an RSRP threshold, an RSRQ threshold, and an SINR threshold.

Correspondingly, the second measurement configuration information mayinclude at least one of the following items:

measurement duration;

a measurement frequency;

a measurement bandwidth or bandwidth part;

a valid measurement area, for example, a cell ID list, a PCI list, asubset or a full set of an RNA ID list, or a subset or a full set of aTA ID list;

a target measurement area, for example, a cell ID list, a PCI list, asubset or a full set of an RNA ID list, or a subset or a full set of aTA ID list;

a measurement type, for example, any one or a combination of RSRP, RSRQ,and an SINR; and

a measurement reporting threshold, for example, any one or a combinationof an RSRP threshold, an RSRQ threshold, and an SINR threshold.

The measurement result measured by the user equipment in the inactivemode may include any one or a combination of the following items:

a meas Id, a measurement frequency, RSRP, RSRQ, a PCI, a CGI, a TAC, anda PLMN Idlist.

Optionally, the first measurement configuration information is used inthe inactive mode.

The method further includes:

if the user equipment switches from the inactive mode to the idle modeand a measurement timer does not expire, performing the followingprocessing on the first measurement configuration information:

clearing access stratum context information stored in the userequipment, where the access stratum context information includes thefirst measurement configuration information and the measurement result;or

clearing the first measurement configuration information and themeasurement result; or

clearing the first measurement configuration information but retainingthe measurement result; or

clearing the measurement result but retaining the first measurementconfiguration information; or

retaining the first measurement configuration information and themeasurement result.

In this optional implementation, the network side device configuresmeasurement configuration information only for the inactive mode in thesystem broadcast message SIB5 and/or the RRC connection release message.

Because the network side device does not configure measurementconfiguration information for the idle mode, when the user equipmentswitches from the inactive mode to the idle mode, the user equipment canperform any one of the following processing on the first measurementconfiguration information:

The user equipment clears stored access stratum context (Access StratumContext, AS context) information. For example, the user equipment maystore the access stratum context information after receiving the RRCconnection release message or an RRC connection suspend message. Theaccess stratum context information includes the measurementconfiguration information (that is, the first measurement configurationinformation) in the inactive mode and the measurement result in theinactive mode. A processing manner of the user equipment may beunderstood as follows: Neither the measurement configuration informationin the inactive mode nor the measurement result measured in the inactivemode is applicable to the user equipment in the idle mode.

Alternatively, the user equipment clears the measurement configurationinformation in the inactive mode and the measurement result measured inthe inactive mode. Similarly, a processing manner of the user equipmentmay be understood as follows: Neither the measurement configurationinformation in the inactive mode nor the measurement result measured inthe inactive mode is applicable to the user equipment in the idle mode.

Alternatively, the user equipment clears the measurement configurationinformation in the inactive mode, but does not clear the measurementresult in the inactive mode. A processing manner of the user equipmentmay be understood as follows: The measurement configuration informationin the inactive mode is not applicable to the user equipment in the idlemode, but the measurement result measured in the inactive mode may beused by the user equipment in the idle mode.

Alternatively, the user equipment clears the measurement result measuredin the inactive mode, but does not clear the measurement configurationinformation in the inactive mode. A processing manner of the userequipment may be understood as follows: The measurement result measuredin the inactive mode is not applicable to the user equipment in the idlemode, but the measurement configuration information in the inactive modemay be used by the user equipment in the idle mode.

Alternatively, the user equipment does not clear the measurementconfiguration information in the inactive mode or the measurement resultmeasured in the inactive mode. A processing manner of the user equipmentmay be understood as follows: Both the measurement configurationinformation in the inactive mode and the measurement result measured inthe inactive mode are applicable to the user equipment in the idle mode.

It should be noted that when the user equipment switches from theinactive mode to the idle mode and the measurement timer expires, theuser equipment automatically clears the measurement configurationinformation in the inactive mode and the measurement result measured inthe inactive mode.

In this implementation, when any one of the following conditions is met,it may be considered that the user equipment switches from the inactivemode to the idle mode.

When the user equipment moves beyond network coverage, it may beconsidered that the user equipment switches from the inactive mode tothe idle mode. Alternatively, when the user equipment initiates an RRCconnection resume request but RRC connection resume fails, it may beconsidered that the user equipment switches from the inactive mode tothe idle mode.

In this embodiment of the present disclosure, the network side devicesends measurement configuration information that is used at least in theinactive mode to the user equipment, so that the user equipment canperform measurement in the inactive mode based on the measurementconfiguration information. Because the user equipment can performmeasurement in the inactive mode, the network side device can quicklyconfigure an SCell of the user equipment and activate the SCell based onthe measurement result in the inactive mode that is reported by the userequipment. It can be learned that this embodiment of the presentdisclosure helps support enhanced rapid carrier activation anddeactivation, so that an enhanced rapid carrier activation anddeactivation technical solution can be improved.
